Anomaly detector

An AI service that helps you foresee problems before they occur

Boost your business systems’ reliability with early problem detection

Easily embed anomaly detection capabilities into your apps so that users can quickly identify problems. Through an API, Anomaly Detector Preview ingests time-series data of all types and selects the best-fitting detection model for your data to ensure high accuracy. Customise the service to detect any level of anomaly and deploy it wherever you need it most. Azure is the only major cloud provider that offers anomaly detection as an AI service.

Powerful inference engine looks at your time-series data set and automatically selects the right algorithm to maximise accuracy for your scenario.

Automatic detection eliminates the need for labelled training data. Save time and stay focused on fixing problems as soon as they surface.

Customisable settings let you fine-tune sensitivity to potential anomalies based on your business’s risk profile.

Speed your time to insights

Fast-track your problem-solving with simple set-up in the Azure portal and real-time anomaly detection. All it takes is three lines of code.

Detect problems for virtually any scenario

There are many types of time-series data – and no one algorithm fits them all. Anomaly Detector looks at your time-series data set and automatically selects the best algorithm from the model gallery to ensure high accuracy for your specific scenario: business incidents, monitoring IoT device traffic, managing fraud, responding to changing markets and more.

Trusted by Microsoft Azure, Office, Windows and Bing

Monitor your product and service health, and deliver reliable customer experiences, using the same anomaly detection service that more than 200 Microsoft product teams rely on.
